Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following critical parameters: resistance value (24.9 Ohms), tolerance (±1%), package type (2512), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and compliance certifications (ROHS3, REACH Unaffected, EAR99).

Direct Equivalent Category: Parts meeting all electrical and mechanical specifications with identical power rating (1W) and standard industrial features.

Upgrade Category: Parts exceeding base specifications through automotive qualification (AEC-Q200) while maintaining all core electrical parameters.

Enhanced Performance Category: Parts with increased power rating (2W) or specialized application features (current sense) that provide functional superset capability within the same package footprint.

All substitute parts listed maintain the 2512 package standard, ±100ppm/°C temperature coefficient, and -55°C ~ 155°C operating range. Dimensional variations remain within acceptable PCB assembly tolerances.

Parameter Comparison

Engineering Selection Recommendations

Frequently Asked Questions (FAQ)

Q: Can RC2512FK-0724R9L replace RC6432F24R9CS in existing designs?

A: Yes. RC2512FK-0724R9L provides direct electrical and mechanical equivalence with identical resistance (24.9 Ω), tolerance (±1%), power rating (1W), package (2512), temperature coefficient (±100ppm/°C), and operating range (-55°C ~ 155°C). Both components feature moisture-resistant construction and ROHS3 compliance.

Q: What is the difference between standard and automotive-qualified substitutes?

A: Automotive-qualified parts (AC2512FK-0724R9L, CRCW251224R9FKEG, RMCF2512FT24R9) carry AEC-Q200 certification, indicating compliance with automotive industry reliability and quality standards. Electrical specifications remain identical to the base part. Selection depends on application requirements and quality assurance protocols.

Q: Is CRM2512-FX-24R9ELF compatible as a direct substitute?

A: CRM2512-FX-24R9ELF provides electrical equivalence (24.9 Ω, ±1%, ±100ppm/°C, -55°C ~ 155°C) but features 2W power rating versus 1W for the base part. This represents a functional superset suitable for applications where higher power dissipation is beneficial or required. Package compatibility (2512) is maintained. Height specification (0.031" max) remains within standard PCB assembly tolerances.

Q: Are dimensional variations between substitute parts significant?

A: Dimensional variations are minor and remain within standard 2512 package tolerances. Length ranges from 0.248" to 0.250", width from 0.122" to 0.126", and height from 0.026" to 0.031". These variations do not affect PCB footprint compatibility or standard reflow assembly processes.

Q: What compliance certifications apply to all listed substitutes?

A: All substitute parts maintain ROHS3 compliance, REACH Unaffected status, EAR99 export classification, and MSL 1 (Unlimited) moisture sensitivity rating. These certifications ensure compatibility with standard manufacturing, storage, and regulatory requirements.

Q: Can substitutes be intermixed in production?

A: Substitutes within the same functional category (standard industrial or automotive-qualified) maintain equivalent electrical performance and package compatibility. Component selection should follow design documentation and procurement specifications. Automotive-qualified parts may be substituted for standard parts when design permits, but reverse substitution requires engineering review.
